i am building a 355 and a friend of mine has one of these laying around i was wondering if it will work in my lt1. is the balance right etc.

SCA-910526
Crankshaft, 1-Piece Seal, Internal Balance, Cast Steel, 3.480 in. Stroke, Chevy, 350

 

???? Anyone ????

 

The crank will work, but you will need to have it balanced to match your specific bob-weight.

IMO the factory crank is better than the Scat 9000 series cast stuff.

 

I agree......you have to watch when your using a different crank on the LT1!!
Any crank will fit and work from 88-94 350 1 piece rear main NON LT1, but it will need rebalanced!

The LT1 crank is VERY strong I have ran 10.60's on spray with that crank!!

 

Do you not have the stock crank? Unless you are going either forged or larger stroke, there is really no need to replace the stock crank.
